ExploreAbout this exam
CM2, Actuarial Mathematics: Models, is one of the technical examinations in the Institute and Faculty of Actuaries' qualification pathway towards Fellowship. It sits after the earlier mathematical foundations subjects and is aimed at candidates who already handle calculus, probability and basic statistical inference and are ready to build and criticise full stochastic models. The syllabus moves from modelling philosophy through distribution theory and estimation into regression and generalised linear models, time series, Markov chains and Markov jump processes, survival models and life-table construction, and finally graduation and mortality projection. Expect the paper to reward judgement as much as algebra: you may be asked to choose a model, justify assumptions, interpret output, and explain limitations, not merely compute a number. Preparation usually means working the tutorial and past-paper style questions by hand under time pressure, keeping a clean formula and distribution reference sheet you have built yourself, and practising written explanations of model choice. Commercial study materials can help, but the syllabus and examiner reports are the calibration points.

What you'll study
About IFoA CM2 preparation
What is the format of the CM2 exam?
It is a written examination requiring full workings, with a mix of calculation and open-ended modelling discussion. The IFoA publishes the current format, sitting arrangements and any computer-based delivery details on its own website, so check there rather than relying on second-hand summaries.
How long is the exam and what is the pass mark?
The IFoA sets and publishes the current duration, pass mark and any pass-list arrangements for each sitting. These change over time, so consult the official IFoA site for the authoritative figures instead of planning around numbers quoted in forums or older study guides.
How difficult is CM2 compared with earlier subjects?
Most candidates find it a step up because it is broad and applied rather than purely computational. The statistical material moves quickly, and the modelling questions demand written justification. The common trap is memorising proofs while neglecting the ability to select a model, state assumptions and interpret results under time pressure.
Can I retake CM2, and how often are sittings held?
Retake rules and sitting frequency are set by the IFoA and can change, so confirm the current policy on its website. In practice candidates plan a retake around the published sitting calendar and use examiner reports from the previous attempt to target weak syllabus areas.
In what order should I study the CM2 syllabus?
A workable order is modelling principles, then distribution theory and estimation, then hypothesis testing, regression and GLMs, then time series and stochastic processes, then Markov chains and jump processes, then survival models and life tables, finishing with graduation and projection. Later topics reuse earlier tools, so resist starting with survival models.
What are the most common reasons candidates fail CM2?
Weak fundamentals in estimation and hypothesis testing, poor time allocation in the exam, and answers that compute a figure without interpreting it. Many also lose marks by omitting assumptions or limitations when asked to discuss a model. Practising full written answers, not just final numbers, addresses most of these.
Do I need to memorise the life table and graduation formulae?
You should know the structure and meaning of life-table functions and the standard graduation approaches well enough to apply and critique them. Exact formulae availability depends on the current exam regulations, which the IFoA publishes, so check what reference material is permitted for your sitting.
How should I prepare in the final weeks?
Work timed questions across all syllabus areas, write out full solutions including commentary, and review examiner reports for presentation and interpretation marks. Keep a one-page summary of distributions, estimators and model assumptions. Avoid learning new topics late; consolidate and rehearse instead.
